The New South Wales Police Minister, Mike Gallacher has defended the Government's commitment to southern Lake Macquarie and northern parts of the Central Coast, where the population is set to boom in coming years.

Around 200 people attended a community cabinet meeting on the coast last night, where Mr Gallacher was challenged over the Government's commitment to boosting frontline services.

The Minister told the meeting the region has not been forgotten.

"We're going to put money into that Belmont area, you're going to see money going into the back of Morisset as well," he said.

"We are pushing up further north as those areas are being developed.

"We are making sure where the growth areas are, particularly in emergency services and law enforcement, try to put the money into those areas for the future."
